Wesley T. Huntress Jr.,Mikhail Ya. Marovof images characteristic of the imaging process in the absence of noise and by examining the properties of object inventories for a test field digitized at a range of sampling intervals. Both analyses indicate that 15μm is an adequate sampling interval for modern Schmidt plates on Type III emulsions.
